DESCRIPTION
The DIR input determines the direction of data flow on the bidirectional buffers. DIR (Active HIGH) enables data flow from A port to B port. DIR (Active LOW) enables data flow from B port to A port. It is available in the commercial temperature range.

The PMOS transistor is turned off when the associated driver is in the low state. The PMOS transistor prevents backdriving current from the signal pins to VCC/CABLE when VCC/CABLE is open or at GND.
